GENERAL DESCRIPTION

The ADG741/ADG742 are monolithic CMOS SPST switches.

These switches are designed on an advanced submicron process

that provides low power dissipation yet high switching speed,

low on resistance, low leakage currents and –3 dB bandwidths of

greater than 200 MHz can be achieved.

The ADG741/ADG742 can operate from a single 1.8 V to 5.5 V

supply, making it ideal for use in battery-powered instruments

and with Analog Devices’ new generation of DACs and ADCs.

As can be seen from the Functional Block Diagrams, with a

logic input of “1” the switch of the ADG741 is closed, while

that of the ADG742 is open. Each switch conducts equally well

in both directions when ON.

The ADG741/ADG742 are available in 6-lead SC70 package.

PRODUCT HIGHLIGHTS

1. 1.8 V to 5.5 V Single Supply Operation. The ADG741/

ADG742 offer high performance, including low on resistance

and fast switching times and is fully specified and guaranteed

with 3 V and 5 V supply rails.

2. Very Low RON (3 Ω max at 5 V, 5 Ω max at 3 V). At 1.8 V

operation, RON is typically 40 Ω over the temperature range.

3. On-Resistance Flatness RFLAT(ON) (1 Ω max).

4. –3 dB Bandwidth >200 MHz.

5. Low Power Dissipation. CMOS construction ensures low

power dissipation.

6. Fast tON/tOFF.

7. Tiny 6-Lead SC70 package.
